Abstract

The utility model provides a multi-furnace end gas stove inflamer device, comprising an air distribution hybrid mechanism which is provided with a blower, a gas burner and an atmosphere mixer, wherein, the gas burner is arranged at the joint of the blower and the atmosphere mixer; a mixed gas-distributing ring which is provided with a gas access and a plurality of gas-distributing pipes which extend out of the gas access, wherein, the gas access is communicated with the atmosphere mixer by gas passages; and a plurality of furnace end inflamers which are connected with a plurality of gas-distributing pipes. The device makes a plurality of furnace end inflamers homogeneously distributed in the stove cavity, thus not only making the caldron heated evenly with a large heating surface area, but also having powerful firepower to ensure cooking duration and time requirement. Furthermore, owing to the multilevel premix of the gas and the air, the combustion is complete, which not only enhances thermal efficiency to achieve energy-saving, but also making the discharge of CO and NO mixtures not overproof. Meanwhile, a miniwatt alternating blower is used to blow the air which saves more than sixty percent of the electricity when compared with the blower caldron stove and lowers the noises of the blower greatly.

Description

Multiple head gas stove burner device

Technical field

The utility model relates to a kind of gas stove burner device, relates in particular to a kind of combustion gas large stove burner apparatus.

Background technology

Existing army, universities and colleges, factory dining room and the employed large stove of some collectiveity canteens thereof mostly are the single furnace head burner of blowing-type.Because the cauldron bore that large stove uses is big, the pot chamber is also big, and the amount of cooking is also big, single furnace head burner generally all is installed in the bottom of a pan centre, and flame concentrates on the bottom of a pan central authorities during burning, causes the bottom of a pan overheated, pot group is not hot, the inequality of being heated, fire is big to be burned, and fire is little not hot, what usually fry is half-cooked dish, and overlong time, the cooking duration and degree of heating is bad, has become the collectiveity canteen a great problem.Because large stove is airtight, draw badly simultaneously, the air blast range burning is poorer, causes the combustion gas waste; And the discharging of CO and NO compound exceeds standard contaminated environment.In addition, be high-power air blast because current blowing-type large stove uses, so the power consumption height, noise is big.

The specific embodiment

As shown in Figure 1, premixed high-efficiency energy-saving combustion gas large stove multiple head burner of the present utility model comprises air distribution mixed organization 1, mixes and divide compression ring 2, a plurality of (being illustrated as 3) furnace head burner 3.Wherein air distribution mixed organization 1 is made up of small-power AC blower fan 11, gas nozzle 12 and general mood blender 13.The power of small-power AC blower fan 11 is between 40-185 watt, and an end of gas nozzle 12 being installed with general mood blender 13 is connected.Gas nozzle 12 is a copper, and the lower end has a plurality of circular fumaroles, is vertically mounted on the end that general mood blender 13 is connected with blower fan 11.General mood blender 13 long 160mm, mid diameter is 84mm, and the end diameter that is connected with elbow 5 is 56mm, and the other end is a square opening, is connected with the flange of blower fan 11.Be equipped with in the cavity in general mood blender 13 and mix gas fan 14, mix the impeller that gas fan 14 is made up of a plurality of flabellums, can do the outward turning campaign, mixed gas fan 14 is positioned at gas nozzle 12 in general mood blender 13 cavitys after, vertical with the spray-hole direction of gas nozzle 12.The jet direction of the fumarole of gas nozzle 12 is identical with the blowing direction of blower fan 11.

Mixing and dividing compression ring 2 external diameters is 85mm, and thick 60mm installs three gas-distributing pipes 25 on every side, becomes on the 45-90 degree angle to stretch out with the central axis of minute compression ring 2 respectively, and tube chamber is connected with the cavity that mixes branch compression ring 2.Mixing and dividing compression ring 2 end mouth internal diameter is 62mm, and is connected with standpipe 4, and this end mouth is the fuel gas mixture import.Air distribution mixed organization 1 makes the combustion gas of premix through airtight passages such as elbow 5, standpipes 4, divides compression ring 2 end mouth injection to divide 2 li of compression rings to mixing from mixing, and enters burner 3 respectively through gas-distributing pipe 25 then.

Furnace head burner 3 is three, is installed in respectively to mix on three gas-distributing pipes 25 that divide compression ring 2.Each burner 3 is made up of shell 31, fire holding cycle 32, branch igniter cap 33 respectively.Basin shape shell 31 external diameter 148mm; high 60mm; fire holding cycle 32 internal diameter 132mm suitable for reading; end mouth internal diameter 82mm divides igniter cap 33 external diameter 42mm, internal diameter 25mm; high 52mm; have a cannelure at the end mouth 20mm place that makes progress, upwards 16mm has a cannelure again, has the circular blast tube that several diameters are 2-3mm respectively on two cannelures.And passage axially with divide igniter cap radially become 10 to spend angles.Combustion gas through premix enters branch igniter cap 33 again through air flue ejection burning from the end mouth of basin shape shell 31 respectively by mixing a plurality of gas-distributing pipes 25 that divide compression ring 2.Air mixture through minute igniter cap 33 ejection collides again on the inwall of fire holding cycle 32, in the annular firing chamber of minute igniter cap 33 and fire holding cycle 32 formation again with outside air mixing rotary combustion, heat loss is little.Fire holding cycle 32 is high aluminum refractory material, and good heat conductivity produces infrared effect during burning, and the flame high-temperature region reaches more than 1300 ℃, has improved the thermal efficiency of large stove, thereby realizes energy-conservation.Because realized the multistage premix of combustion gas and air, it is more abundant to burn, thermal efficiency height not only, C0, N0 mixture discharge not overproof, have also realized environmental requirement.In addition, because the multiple head burner flame is evenly distributed, the fast duration and degree of heating of cooking is suitable, solved single furnace head burner enamelware pot at the bottom of, flame distribution is inhomogeneous, cause to be burned and to fry the not problem of cooked food.This large stove burner is applicable to army, universities and colleges, factory, collectiveity canteen etc.

It will be appreciated by those skilled in the art that above-mentioned embodiment only plays explanation effect of the present invention, and should not be construed as any restriction that it is done.
